Installing the Main Hub
9.2.4 Interfacing LGCell to Base Stations
WARNING: Exceeding the maximum input power could cause failure
of the Main Hub (refer to Section 7.1 on page 7-3 for maximum power
ratings). Attenuators may be required to limit the maximum composite
power into the Main Hub.
Connecting a Main Hub to a Roof-top Antenna
LGC Wireless recommends that you use a lightning arrestor or surge protector in a
roof-top antenna configuration. Insert the lightning arrestor or surge protector
between the roof-top antenna and the repeater that is connected to the Main Hub.
1. Connect an N-male to N-male coaxial cable to the roof-top antenna.
2. Connect the other end of the N-male to N-male coaxial cable to the grounded
surge suppressor.
3. Connect an N-male to N-male coaxial cable to the grounded surge suppressor.
4. Connect the other end of the N-male to N-male coaxial cable to the repeater.
5. Connect an N-male to N-male coaxial cable to the repeater.
6. Connect the other end of the N-male to N-male coaxial cable to the circulator
1 connector.
7. Connect an N-male to N-male coaxial cable to the circulator 2 connector.
8. Connect the other end of the N-male to N-male coaxial cable to the FORWARD
simplex connector on the Main Hub.
Attenuation may be required to achieve the desired RF output at the RAU.
9. Connect an N-male to N-male coaxial cable to the circulator 3 connector.
10. Connect the other end of the N-male to N-male coaxial cable to the REVERSE sim-
plex connector on the Main Hub.
